Modeling of PM10 dispersion from coal thermal power plants Kostolac A and B

Abstract

Serbian electricity production is predominantly based on coal power plants, which produce large sources of particle matter emissions. Modeling of PM10 dispersion from the combustion process of thermal power plants Kostolac A and B (TEKO A and TEKO B) is performed in order to examine the impact of the newly built TEKO B’s Flue Gas Desulphurization (FGD) units, and the results are presented in this paper. Two scenarios are discussed within this study, “without FGD” and “with FGD”. The AERMOD dispersion model, with hourly meteorological data (five years in row) from a representative measuring station, is used as modeling tool. Despite the large reduction in emission values of TEKO B after installation of the FGD system, the results achieved indicate that the FGD has had no significant impact on air quality in the observed domain, due to dominant influence of TEKO A and characteristics of TEKO B stack/s.
